Many organizations use Kubernetes to orchestrate their containerized applications. But because Kubernetes is complex, application developers may take some time to ramp up on the intricacies of monitoring a Kubernetes environment. This means that teams often need to create internal documentation and offer hands-on training to bridge the knowledge gap.

Software operators are steadily revolutionising how we deploy and run complex distributed systems. They offer the promise of low-intervention, self-driving software – ideally leading to service reliability gains and better uptime. For an introduction to Kubernetes operators, check out our introductory webinar or download our guide to Kubernetes operators.

Danielle Burrow and Munjal Munshi contributed to this blog post. Every modern enterprise is building applications to generate revenue, connect people and systems, and automate processes. Modern applications, architected to take advantage of the flexibility and efficiencies of the cloud, are projected by IDC to surpass traditional apps by 2024.

If you are using Argo CD, you may be already familiar with how the Application CRD (Custom Resource Definition) object helps you logically group together your Kubernetes Manifests. The Application object is the atomic unit of work in Argo CD, and you should think of all your Kubernetes objects that are in an Application as a single entity. Applications are also autonomous. Meaning that, by design, one Application doesn’t know about the status or health of another Application.

The biggest question facing many businesses today is how to improve the efficiency and agility of their application delivery processes. Along the journey to infrastructure modernization, do they continue to maintain applications as-is, or do they need to be migrated, upgraded or replaced? This blog attempts to answer some of these questions. Take any popular enterprise app, like your Oracle business suite, or even a custom-built application, and it will typically follow a three-tier architecture.

Logs are key to monitoring the performance of your applications. Kubernetes offers a command line tool for interacting with the control plane of a Kubernetes cluster called Kubectl. This tool allows debugging, monitoring, and, most importantly, logging capabilities. There are many great tools for SREs. However, Kubernetes supports Site Reliability Engineering principles through its capacity to standardize the definition, architecture, and orchestration of containerized applications.

Today, it is crucial that an organization’s application’s scalability matches its growth tempo. If you want your client’s app to be robust and easy to scale, you have to make the right architectural decisions. Cloud native applications are proven more efficient than their traditional counterparts and much easier to scale due to containerization and running in the cloud.

CrashLoopBackOff is a Kubernetes state representing a restart loop that is happening in a Pod: a container in the Pod is started, but crashes and is then restarted, over and over again. Kubernetes will wait an increasing back-off time between restarts to give you a chance to fix the error. As such, CrashLoopBackOff is not an error on itself, but indicates that there’s an error happening that prevents a Pod from starting properly.

In this tutorial, you will learn how to build a custom ASP.NET Core container with Docker and host the container image on Azure Container Registry, a platform owned by Microsoft that allows you to build, store, and manage container images in a private registry.

Zero Trust security is gaining attention and momentum as a security approach or mindset that can improve the security posture of enterprises as they continue to battle hackers. Because of this widespread attention on Zero Trust, every software security vendor seems to be jumping on the Zero Trust bandwagon. However, Zero Trust is not a product or service. No single product or vendor can sell you Zero Trust security.

When we say “logs” we really mean any kind of time-series data: events, social media, you name it. See Jordan Sissel’s definition of time + data. And when we talk about autoscaling, what we really want is a hands-off approach at handling Elasticsearch/OpenSearch clusters. In this post, we’ll show you how to use a Kubernetes Operator to autoscale Elasticsearch clusters, going through the following with just a few commands.

One of the greatest challenges that operators and developers face is infrastructure provisioning: it should be resilient, reliable, reproducible and even audited. This is where Infrastructure as Code (IaC) comes in. In the last few years, we have seen many tools that tried to solve this problem, sometimes offered by the cloud providers (AWS CloudFormation) or vendor-agnostic solutions like Terraform and Pulumi.

Kubernetes may provide an abundance of benefits, but those who are using it may be well aware that it often requires quite a bit (or even a lot!) of effort and skill to run the platform independently. So – rather than having to put up with it on their own, organizations are able to pay for a managed Kubernetes service instead. This is where Google Kubernetes Engine (GKE), Azure Kubernetes Service (AKS), and Amazon Elastic Kubernetes Service (EKS) come in.

To avoid application downtime and data loss during Kubernetes clusters outage, platform and application operators need to utilize backups for recovery. These backups should contain both the application’s persistent data alongside its configurations, which can be restored to the same or different cluster to get back into production more quickly.

When people hear ‘microservices’ they often think about Kubernetes, which is a declarative container orchestrator. Because of its declarative nature, Kubernetes treats microservices as entities, which presents some challenges when it comes to troubleshooting. Let’s take a look at why troubleshooting microservices in a Kubernetes environment can be challenging, and some best practices for getting it right.

Github’s, “Github Actions” CI/CD tooling is becoming an increasingly popular option for developers. I've personally worked with several Cycle users who are adopting Github Actions as part of their deployment solution and we've found that when pairing GH actions with Cycle it makes for a simple, yet powerful combination. Today we’ll stroll through a basic example of using Github Actions alongside the Cycle platform.

With the emergence of new programming languages, libraries, packaging systems, and dependencies, the open source landscape has become more diverse. At the same time, companies are finding it more and more complex to package and deliver open source software. This creates a massive challenge for independent software vendors (ISVs), large enterprises, and other organizations that need to control their software supply chain lifecycles while adhering to industry standards and best practices.

In part two, I will cover: Microservices Architecture Overview: New Challenges for Monolithic Architecture As an application grows, so does the amount of code written. This can quickly overwhelm the development environment every time it needs to be opened and run. As you must deploy everything in one place, this approach means that the transition to another programming language, or other technologies becomes a big problem.

Modern Kubernetes environments are becoming increasingly complex. In 2021, Datadog analyzed real-world usage data from more than 1.5 billion containers and found that the average number of pods per organization had doubled over the course of two years. Organizations running containers also tend to deploy more monitors than companies that don’t leverage containers, pointing to the increased need for monitoring in these environments.

After months in development, we are thrilled to announce the launch of Cycle.io's support for NVIDIA GPUs (Beta). Combined with an already powerful platform that enables developers to focus on building, rather than managing, the addition of GPUs will further empower the development of accelerated applications which require a higher level of compute power.

Organizations are becoming more aware of the advantages of upgrading their continuous integration and continuous delivery (CI/CD) pipelines and moving them to the cloud, from lowering infrastructure costs to eliminating security threats. But carrying out a transfer is challenging, especially when a variety of platforms and technologies are involved.

5G is seeing rapid adoption due to its promise of high speed, seamless delivery and low latency, that enables it to deliver new and exciting revenue-generating services.
